Mayank Rana ea1adfd7d0 PCI: starfive: Enable controller runtime PM before probing host bridge 
[ Upstream commit 6168efbeba ]

A PCI controller device, e.g., StarFive, is parent to PCI host bridge
device. We must enable runtime PM of the controller before enabling runtime
PM of the host bridge, which will happen in pci_host_probe(), to avoid this
warning:

  pcie-starfive 940000000.pcie: Enabling runtime PM for inactive device with active children

Fix this issue by enabling StarFive controller device's runtime PM before
calling pci_host_probe() in plda_pcie_host_init().
